Sadly unreal engine 5 does not support windows 7, windows 10 is the minimum version that will work. No fix for this i'm afraid.

That's a pity. It seems that I should change my computer.
but thank you for paying attention to the opinions of our players. At the same time, I hope you can create more similar games. It would be better if the configuration requirements can be lower. I believe more people will participate in this game
